[0026] Example 1

[0027] As mentioned in the background section, in order to solve the problems in the prior art, this application provides a filtration device for washing vegetables, placed at the end of the conveying direction of the washing water tank 8, comprising:

[0028] The support frame is equipped with a conveyor belt 1, which is used to receive the vegetables that have been washed in the washing tank 8 and transport the vegetables to the next process. The first screen holes are evenly distributed on the conveyor belt 1.

[0029] Water tank 2 is located below conveyor belt 1, and the top of water tank 2 has a first opening;

[0030] Two guide channels 3 are respectively located at both ends of the conveyor belt 1 along the first direction. The end of the guide channel 3 away from the conveyor belt 1 overlaps with the first opening, so that the water filtered by the conveyor belt 1 can enter the water tank 2 along the guide channel 3.

[0031] like Figure 1As shown, the first direction is the length direction of the conveyor belt 1, and the second direction is the width direction of the conveyor belt 1. The support includes four first support columns 13 for supporting the conveyor belt 1. The conveyor belt 1 includes two connecting plates extending along the first direction. Two guide rollers are rotatably connected between the two connecting plates. A belt body is tensioned on the two guide rollers. The belt body is made of polyester fiber and has multiple first sieve holes distributed in a matrix. Baffles are also provided on the two connecting plates to prevent vegetables or water from spilling from the conveyor belt 1 during the conveying process. A water tank 2 is located below the conveyor belt 1 and has a first opening at its top. Multiple second support columns 14 are also provided at the first opening for supporting the conveyor belt 1. Two guide channels 3 are respectively connected to both ends of the conveyor belt 1. The end furthest from the conveyor belt 1 is connected to the first opening. After the vegetables are washed, they are transported to the conveyor belt 1 along with the water in the washing tank 8. The vegetables move with the conveyor belt 1. The water is filtered through the first screen and falls directly into the water tank 2 through the first opening, or falls onto the guide channel 3 and enters the water tank 2 along the guide channel 3. The ends of the first support column 13 and the second support column 14 near the conveyor belt 1 are both provided with strip-shaped holes. The two connecting plates are provided with mounting holes corresponding to the strip-shaped holes. The conveyor belt 1 can be fixed by using bolts that pass through both the strip-shaped holes and the mounting holes. At the same time, by changing the position of the mounting holes on the strip-shaped holes, the tilt angle of the conveyor belt 1 can be adjusted, which facilitates the docking of the conveyor belt 1 with other equipment.

[0032] By setting up a conveyor belt 1 with a first screen hole, the washed vegetables are filtered while being transported. The filtered water enters the water tank 2 and can be transported back to the washing water tank 8 for washing vegetables. Compared with the traditional method of using a vibrating screen for filtration, this method improves production efficiency and avoids the damage to the equipment caused by using a vibrating motor.

[0033] In a preferred embodiment, a filter structure is also included, which covers the first opening and has a second screen hole evenly distributed thereon; the ends of the two guide channels 3 away from the conveyor belt 1 are respectively connected to the filter structure.

[0034] In a preferred embodiment, the aperture of the second sieve aperture is smaller than that of the first sieve aperture.

[0035] like Figure 1 As shown, the filter structure covers the first opening, and a second screen is evenly distributed on it for secondary filtration of the water after it has been filtered by the conveyor belt 1. The second screen with a smaller pore size can filter out residual impurities in the water, so that the filtered water can be transported to the cleaning water tank 8 for reuse after entering the water tank 2.

[0036] In a preferred embodiment, the filter structure includes a sieve plate 4, which is disposed at a first opening and has second sieve holes evenly distributed thereon; the sieve plate 4 has a first end and a second end, the height of the first end being higher than the height of the second end.

[0037] In a preferred embodiment, the filter structure further includes a collection tank 5, which is located at the first opening near the second end and has second sieve holes evenly distributed on it; a pull rod 6 is fixed on the collection tank 5.

[0038] like Figure 1 As shown, the sieve plate 4 is approximately a rectangular planar structure, located at the first opening and below the conveyor belt 1; two guide channels 3 overlap on the sieve plate 4, allowing the water filtered by the conveyor belt 1 to undergo secondary filtration by the sieve plate 4. The sieve plate 4 is inclined relative to the horizontal direction. The collection tank 5 is also located at the first opening, connected to the second end of the sieve plate 4. After the water undergoes secondary filtration through the sieve plate 4, the filtered impurities adhere to the sieve plate 4 and are washed by the subsequent falling water before flowing along the sieve plate 4 into the collection tank 5. The sieve plate 4 and the collection tank 5 are both located at the first opening for easy disassembly and cleaning. When the collection tank 5 is full of impurities, the collection tank 5 can be lifted by the pull rod 6 to separate it from the water tank 2, thereby cleaning the collection tank 5. In this embodiment, baffles are also provided on both sides of the sieve plate 4 to prevent water from overflowing.

[0039] In a preferred embodiment, a scraper 7 is also provided at the end of the conveyor belt 1 located in its conveying direction.

[0040] like Figure 1 As shown, when the conveyor belt 1 filters the water once, some impurities are filtered out of the water and then adsorbed onto the conveyor belt 1. The scraper 7 is located below the end of the conveyor belt 1 in the conveying direction and can scrape off the part of the belt body located below the guide roller to clean the impurities attached to the belt body.

[0041] In a preferred embodiment, a purging assembly is also included. The purging assembly includes a drive pump, which is connected to a purging pipe. The purging pipe is located at the end of the conveyor belt 1 in the conveying direction and passes through the inside of the conveyor belt 1 in a second direction. The second direction is perpendicular to the first direction. A plurality of purging holes are distributed on the purging pipe, and the purging holes are arranged toward the guide groove 3 near the end of the conveyor belt 1 in the conveying direction.

[0042] like Figure 1 As shown, the drive pump can be an air pump or water pump as in the prior art. The purge pipe passes through the belt body along the width direction and is fixed to the connecting plates on both sides. One end of the purge pipe passes through the connecting plate and is connected to the output end of the drive pump. The part between the two connecting plates has multiple purge holes facing the guide groove 3. The drive pump delivers air or water to the purge pipe and blows it towards the belt body through the purge holes. This can purge the impurities on the belt body that have not been scraped off by the scraper 7, causing the impurities to fall onto the guide groove 3 and fall down with the water on the guide groove 3, eventually entering the collection tank 5.

[0043] Example 2

[0044] This application also provides a filtered water circulation cleaning system, including a vegetable cleaning filter as described above, and a cleaning device, which includes a cleaning tank 8. The cleaning tank 8 is equipped with a vortex component, which is connected to a water tank 2. The vortex component is used to pressurize the water in the water tank 2 and deliver it to the cleaning tank 8, so as to generate a vortex in the cleaning tank 8 to clean the vegetables.

[0045] like Figure 2 As shown, the outlet of the washing tank 8 is connected to the starting point of the conveyor belt 1 in the conveying direction. The washing tank 8 is equipped with a vortex component, which can pressurize the water in the water tank 2 and deliver it to the washing tank 8, so as to generate a vortex in the washing tank 8 to wash the vegetables. Under the action of the vortex component, the vegetables and a part of the water are delivered to the conveyor belt 1. The vegetables move along the conveyor belt 1, and the water enters the water tank 2 after being filtered twice for the next cycle.

[0046] In a preferred embodiment, the vortex assembly includes a circulation pump 9, the input end of which is connected to the water tank 2, and the output end of which is connected to a plurality of vortex tubes 10. A plurality of vortex branch pipes are connected to the vortex tubes 10, and the free ends of the plurality of vortex branch pipes pass through the cleaning water tank 8 and are connected to vortex nozzles.

[0047] like Figure 2 As shown, in this embodiment, two circulation pumps 9 are installed below the cleaning water tank 8. The input ends of the two circulation pumps 9 are connected to the water tank 2, and the output ends of the two circulation pumps 9 are connected to three vortex tubes 10. The input ends of the three vortex tubes 10 are respectively equipped with switch valves to control the connection of the three vortex tubes 10. Two of the vortex tubes 10 are located on the same side of the cleaning water tank 8 and are distributed in a vertical direction. Both of them are connected to multiple vortex branch pipes. The free ends of the multiple vortex branch pipes pass through the cleaning water tank 8 and are connected to vortex nozzles. The last vortex tube 10 is located on the side of the cleaning water tank 8 away from the conveyor belt 1, and its free end also passes through the cleaning water tank 8 and is connected to the vortex nozzle.

[0048] In a preferred embodiment, the bottom of the cleaning water tank 8 is provided with a filter screen, and the bottom of the tank is also connected to a drain pipe 11. The free end of the drain pipe 11 is connected to the water tank 2, and a drain outlet 12 is provided on it.

[0049] like Figure 2As shown, a filter screen is located at the bottom of the cleaning tank 8, between the vortex nozzle and the drain outlet 12. It is used to filter out impurities in the water in the cleaning tank 8 before it enters the drain pipe 11. Switch valves are also provided between the drain pipe 11 and the water tank 2, as well as at the drain outlet 12. The water in the cleaning tank 8 can enter the water tank 2 through the drain pipe 11 after being filtered by the filter screen, so as to replenish the water stored in the water tank 2 and prevent the water in the water tank 2 from being pumped out under the action of the two circulation pumps 9, thus preventing the circulation from being interrupted. The drain outlet 12 is used to discharge the water in the equipment after the cleaning system stops working.

[0050] Working principle: Initially, sufficient water is injected into the water tank 2 and the washing tank 8. Two circulation pumps 9 are started. Under the action of the circulation pumps 9, the water in the water tank 2 passes through the vortex nozzles, creating a vortex in the washing tank 8, thereby washing the vegetables. Impurities on the vegetables fall off under the action of the vortex. A portion of the water in the washing tank 8 flows back to the water tank 2 through the drain pipe 11, ensuring sufficient water for circulation. The vegetables and a portion of the water are transported to the conveyor belt 1. The vegetables move along the conveyor belt 1, while the water enters the water tank 2 after being filtered twice by the conveyor belt 1 and the filter structure for the next circulation. In this embodiment, the washing system includes washing equipment and filtration equipment. One washing equipment and one filtration equipment can form a washing and filtration group. In actual use, the number of washing and filtration groups can be set according to the situation, and no special limitation is made here.

[0051] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. The above descriptions are only preferred embodiments of this application. It should be noted that due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of this invention, and can also combine the above technical features in an appropriate manner.
